Abstract
Description
- 1. Field of the Invention
- This invention relates to a multi-functional flow control valve for water treatment systems.
- 2. Description of the Prior Art
- All existing industrial and household water treatment systems depend on switching function of multi-functional flow control valves for the purposes of softening, purification, backwash and regeneration of effluent. Typical of the valves on current market are Fleck valves and Autotrol valves. The Fleck valve, produced by Pentair, Inc., USA, has several layers of seal rings in a valve body thereof, which are separated by several working of plastics, thereby allowing space therebetween. The seal rings are sealed against the valve body on an external side thereof and against a cylinder encapsulated piston on an internal side thereof. The encapsulated piston is drawn up and down and positioned at different positions to form different flow channels. That is, the performance of the multi-port valve is realized by the encapsulated piston being placed at different positions along the axis. The Autotrol valve, produced by Autotrol Corporation, also in USA, has several valves arranged along a band in a valve body thereof. A cam rotor axis with several cams at different angles is worked by an engine. As the cam rotor axis rotates, the cams at different angles are open to certain ports but closed to others, thereby to realize different flow channels and the desired functions.
- Apparently, some types of multi-functional flow control valves exist. One combines several valves into one valve body, which results in a more complicated structure, difficulty in manufacturing, bigger size and inconvenience in installation. Another type of flow control valves connects several external valves and the flow is controlled by opening and closing different valves in different positions. This type is difficult to install and inconvenient to operate. The third type features the movements of the encapsulated piston in the sealed cavity. The flow is controlled and directed by locating the encapsulated piston in different positions. However, the problem with this structure is that the flows in those channels are easily mixed and thus undermine the treatment effect.
- An object of the present invention is to provide a multi-functional flow control valve of water treatment systems which features a simplified and compact structure and easy operation for softening, purification, backwash and regeneration of effluent.
- To achieve the above-mentioned object, a multi-functional flow control valve of water treatment systems developed employing the theory of hermetical head faces in accordance with a preferred embodiment of the present invention is provided. The valve includes a valve body having a water inlet port, a water outlet port and an effluent outlet. A valve core connected with a valve rod is placed inside the valve body. The valve body defines a flow channel therein for connecting with an inside and an outside of a filter element of the water treatment system, respectively. The valve core includes a moving valve disk and a fixed valve disk of which head faces are aligned hermetically rotationally. The moving valve disk is connected to the valve rod. The fixed valve disk defines a plurality of through holes therein which are connected to the water inlet port, the water outlet port and the effluent outlet, respectively. The moving valve disk defines a through hole and two blind recesses therein. By rotating the moving valve disk, the through hole and the blind recesses in the moving valve disk are aligned with corresponding holes in the fixed valve disk for forming different liquid flow channel thereby realizing control of a flow. The through hole and the blind recesses in the moving valve disk and the plurality of through holes in the fixed valve disk are allocated on a same turning circle.
- The principles for design of the invention is basically that different ports are allocated on a plane circle, and when the moving valve disk is rotated, some ports are opened and some are closed.
- When under use, the moving valve disk is rotated manually or by an engine, and different controlled cycles of softening, backwash, regeneration, fast rinse, etc, are realized by aligning different through holes and blind recesses on the moving and the fixed valve disks. On a whole the present invention features easy operation, a compact structure, easy manufacturing, quick installation, a wide range of applications in various industrial and household water treatment systems and improved quality of water treatment.

FIGS. 1-3 , there are awater inlet port 5, awater outlet port 6 and aneffluent outlet 7 in avalve body 1, which is connected separately to an inside and an outside of afilter element 18 of a water treatment system through a flow channel. Aleg flow channel 16 is formed in the flow channel from thewater inlet port 5 to thefilter element 18 and theleg flow channel 16 fixes anejector nozzle 17 inside. Abrine inlet port 20 is defined near theejector nozzle 17 in thevalve body 1, which may connect with abrine tank 21 of the water treatment system. A valve core of thevalve body 1 includes a movingvalve disk 3 and a fixedvalve disk 2, of which head faces are aligned hermetically rotationally. The movingvalve disk 3 is connected to avalve rod 4. The fixedvalve disk 2 defines a throughhole 8 in a center of the head face thereof to connect with theeffluent outlet 7 of thevalve body 1 and six through holes along a circle around the center of the head face thereof, among which a throughhole 9 is connected to the outside of thefilter element 18, throughholes filter element 18, a throughhole 11 is connected to thewater outlet port 6, and throughholes ejector nozzle 17, respectively. The movingvalve disk 3 forms a radialblind recess 13 from a center to an edge in the hermetical aligning head face thereof and ablind recess 14 shaped as a circular arc around the center in the hermetical aligning head face thereof. The movingvalve disk 3 further forms a throughhole 15 which permanently opens to thewater inlet port 5. The holes and the blind recesses in the fixedvalve disk 2 and the movingvalve disk 3 are allocated along a same turning circle for the purpose of aligning. The fixedvalve disk 2 and the movingvalve disk 3 can be made of ceramics or other material. If the material is not hard enough, a separating bar can be placed within some bigger holes like the throughholes - When in operation, the
valve body 1 is fixed on awater treatment tank 19, and thefilter element 18 is fixed in thewater treatment tank 19, or filtering material can be placed directly inwater treatment tank 19 instead of thefilter element 18. Normally a flow between thevalve body 1 and thefilter element 18 passes through adistributor 22 in thewater treatment tank 19. Thefilter element 18 made from activated carbon or sand leach can be used for purification and thefilter element 18 made from resin is used for softening. The system can be operated manually or by electricity. In most industrial water treatment systems, thevalve rod 4 is worked by engines and a switching between different cycles is realized by a variation in the aligning positions of the different holes in the movingvalve disk 3 and the fixedvalve disk 2. - The following working process of the water treatment system using a
resin filter element 18 is provided to illustrate the full range of working cycles of this embodiment. Brine or other regenerating material should be added for the regeneration of resin material. The water treatment system can be equipped with thebrine tank 21 connecting with thebrine inlet port 20 of thevalve body 1 by awater inlet valve 23. - In a softening cycle, as shown in
FIGS. 4 and 5 , the throughhole 15 in the movingvalve disk 3 is aligned with the throughhole 9 in the fixedvalve disk 2 and theblind recess 14 covers the throughholes water inlet port 5 passes by the throughhole 15 into the throughhole 9, then into thewater treatment tank 19. After filtered by thefilter element 18, the water flow runs through thedistributor 22, the throughhole 10, theblind recess 14 and the throughhole 11 before it flows out through thewater outlet port 6. In this cycle when the water flow runs through thewater inlet port 5 to the flow channel outside thefilter element 18, theblind recess 13 covers the throughholes leg flow channel 16. - In a backwash cycle, as shown in
FIGS. 6 and 7 , the throughhole 15 in the movingvalve disk 3 is aligned with the throughhole 10 in the fixedvalve disk 2 and theblind recess 13 covers the throughholes valve disk 2. The water flow runs by the throughholes distributor 22, reaches the inside of thefilter element 18, then backwashes the residue accumulated in thefilter element 18 and becomes waste water which passes through theblind recess 13 into the throughhole 8 and outpours from theeffluent outlet 7. - In a regeneration cycle through in-taking salt, as shown in
FIGS. 8 and 9 , the throughhole 15 in the movingvalve disk 3 is aligned with the throughhole 24 in the fixedvalve disk 2 and theblind recess 14 covers the throughholes water inlet port 5 passes by the throughhole 15, enters the throughhole 24, and jets out through theejector nozzle 17 at the end of theleg flow channel 16. In this cycle, the water flow causes negative pressure at the outlet port of theejector nozzle 17, i.e., thebrine inlet port 20 of thevalve body 1, after jetting. The brine in thebrine tank 21 is in-taken by thebrine inlet port 20 through thewater inlet valve 23. The mixed flow of the brine and the water runs from the throughhole 25 to the throughhole 9 through theblind recess 14, then into thewater treatment tank 19. The flow is regenerated through thefilter element 18, passes thedistributor 22 into the throughhole 10, enters the throughhole 8 via theblind recess 13 and outpours from theeffluent outlet 7. When a water level of thebrine tank 21 falls to a pre-defined point, thewater inlet valve 23 shuts automatically. - After the brine in-taking cycle is completed, since the brine in the
brine tank 21 has been used, water has to be added. As shown inFIGS. 11 and 11 , the throughhole 15 in the movingvalve disk 3 is aligned with the throughhole 25 in the fixedvalve disk 2 and theblind recess 13 covers the throughholes ejector nozzle 17 from the throughhole 15 through the throughhole 25 and theleg flow channel 16. As the outlet port of theejector nozzle 17 is thinner, most of the flow runs into thebrine tank 21 through thebrine inlet port 20. When enough water accumulates, salt can be added into thebrine tank 21 to provide the brine for regeneration. The whole process is easily done. A small portion of water flows back through theejector nozzle 17 and the throughhole 24, enters the throughhole 8 via theblind recess 13, and outpours from theeffluent outlet 7. - In a fast rinse cycle, as shown in
FIGS. 12 and 13 , the throughhole 15 in the movingvalve disk 3 is aligned with the throughhole 9 in the fixedvalve disk 2 and theblind recess 13 covers the throughholes valve disk 2. The water flow runs by the throughholes filter element 18, and washes the residue brine out of thefilter element 18. The residue brine runs through thedistributor 22, the throughhole 12, theblind recess 13 and the throughhole 8 and outpours from theeffluent outlet 7. - Only in a purification cycle, the
filter element 18 made from activated carbon material or sand leach can be added into thewater treatment tank 19, and no regeneration is needed. As shown inFIG. 14 , thebrine inlet port 20 can be blocked. Similar working procedures are followed for purification, backwash and fast rinse. In the course of production, theleg flow channel 16, theejector nozzle 17 and thebrine inlet port 20 can be omitted in thevalve body 1 and the throughhole 24 and the throughhole 25 can also be omitted, which makes a simpler structure. -
FIGS. 25 and 26 show another moving valve disk and another fixed valve disk of the second embodiment, respectively. - In the course of softening, as shown in
FIGS. 15 and 16 , the throughhole 15 in the movingvalve disk 3 is aligned with the throughhole 9 in the fixedvalve disk 2 and the lowerblind recess 14 in the movingvalve disk 3 covers the throughholes blind recess 13 in the movingvalve disk 3 is only connected to the throughhole 8 in the fixedvalve disk 2 and no through channel is formed. In this cycle, the water flow runs into the throughhole 9 in the fixedvalve disk 2 by the throughhole 15 in the movingvalve disk 3. As the throughhole 9 leads to a top of thewater treatment tank 19, the water flow runs into the top of thewater treatment tank 19 and down through a resin layer where the water is changed into softened water. The softened water then returns to a central channel of thewater treatment tank 19 through a lower distributor, and runs upward to the throughhole 10 in the fixedvalve disk 2. As the throughhole 10 and the throughhole 11 are connected by theblind recess 14 in the movingvalve disk 3, the softened water flows into the throughhole 11 through the throughhole 10. Since the throughhole 11 leads to thewater outlet port 6, the softened water flows out from thewater outlet port 6. - In the backwash cycle, as shown in
FIGS. 17 and 18 , the throughhole 15 in the movingvalve disk 3 is aligned with the throughhole 10 in the fixedvalve disk 2 and the lowerblind recess 13 in the movingvalve disk 3 covers the throughholes blind recess 14 in the movingvalve disk 3 is only connected to the throughhole 12 in the fixedvalve disk 2 and no through channel is formed. In this cycle, the water flow runs into the throughhole 10 in the fixedvalve disk 2 by the throughhole 15 in the movingvalve disk 3. As the throughhole 10 leads to the central channel of thewater treatment tank 19, the water flow runs into the central channel and down through the lower distributor into thewater treatment tank 19. The water flow then returns upward to the resin layer and reaches the throughhole 9 in the fixedvalve disk 2. As the throughhole 9 and the throughhole 8 are connected by theblind recess 13 in the movingvalve disk 3, the water flow runs into the throughhole 8 through the throughhole 9. As the throughhole 8 leads to theeffluent outlet 7, after the backwash cycle, the waste water flow runs out from theeffluent outlet 7. - In the regeneration cycle, as shown in
FIGS. 19 and 20 , the throughhole 15 in the movingvalve disk 3 is aligned with the throughhole 11 in the fixedvalve disk 2 and the lowerblind recess 13 in the movingvalve disk 3 covers the throughholes blind recess 14 in the movingvalve disk 3 is only connected to the throughhole 9 in the fixedvalve disk 2 and no through channel is formed. At this time, the water flow runs into the throughhole 11 in the fixedvalve disk 2 by the throughhole 15 in the movingvalve disk 3. As the throughhole 11 leads to thewater outlet port 6, a portion of the water flows directly runs out from thewater outlet port 6. Another portion of the water flow jets out from theejector nozzle 17. After jetting, the flow causes negative pressure at the outlet port of theejector nozzle 17, i.e., thebrine inlet port 20 of thevalve body 1, thereby to open thewater inlet valve 23 of thebrine tank 21. The brine in thebrine tank 21 is in-taken by thebrine inlet port 20 through thewater inlet valve 23. The mixed flow of the brine and the water runs to the top of thewater treatment tank 19, flows down through the resin layer, and reaches the lower distributor. Then the flow runs upward through the central channel into the throughholes valve disk 2. As the throughhole 10 and the throughhole 8 in the fixedvalve disk 2 are connected by theblind recess 13 in the movingvalve disk 3, the water flow runs by the throughhole 10 to the throughhole 8. As the throughhole 8 leads to theeffluent outlet 7, the waste water after brine in-taking flows out from theeffluent outlet 7. - In the fast rinse cycle, as shown in
FIGS. 21 and 22 , the throughhole 15 in the movingvalve disk 3 is aligned with the throughhole 9 in the fixedvalve disk 2 and the lowerblind recess 14 in the movingvalve disk 3 is only connected with the throughholes 10 and no through channel is formed. The upperblind recess 13 in the movingvalve disk 3 covers the throughhole 12 and the throughhole 8, which are thus connected. In this phase, the water flow runs into the throughhole 9 in the fixedvalve disk 2 by the throughhole 15 in the movingvalve disk 3. As the throughhole 9 leads to the top of thewater treatment tank 19, the water flow runs into the top of thewater treatment tank 19 and down through the resin layer where the water flow washes down the brine regenerated by the resin layer which has taken in the brine. The water flow then returns to the central channel through the lower distributor, and runs upward to the throughhole 10 and the throughhole 12 in the fixedvalve disk 2. As the throughhole 12 and the throughhole 8 is connected by theblind recess 14 in the movingvalve disk 3, the water flow runs into the throughhole 8 by the throughhole 10 and the throughhole 12. As the throughhole 8 leads to theeffluent outlet 7, the water after the cycle of fast rinse flows out from theeffluent outlet 7. - When water is added to the
brine tank 21, as shown inFIG. 23 andFIG. 24 , the throughhole 15 in the movingvalve disk 3 is aligned with the throughhole 9 in the fixedvalve disk 2 and the lowerblind recess 14 in the movingvalve disk 3 covers the throughhole 10 and the throughhole 11, which are thus connected. The upperblind recess 13 in the movingvalve disk 3 is only connected to the throughhole 9 in the fixedvalve disk 2 and no through channel is formed. In this phase, the water flow runs into the throughhole 9 in the fixedvalve disk 2 by the throughhole 15 in the movingvalve disk 3. As the throughhole 9 leads to the top of thewater treatment tank 19, the water flow runs into the top of thewater treatment tank 19 and down through the resin layer where the water is changed into softened water. The softened water then returns to the central channel of thewater treatment tank 19 through lower distributor and runs upward to the throughhole 10 in the fixedvalve disk 2. As the throughhole 10 and the throughhole 11 are connected by theblind recess 14, the softened water flows into the throughhole 11 via the throughhole 10. As the throughhole 11 leads to thewater outlet port 6, the softened water flows out from thewater outlet port 6. A portion of the water flow passes through a pipe of theejector nozzle 17 and a brine in-taking valve into thebrine tank 21. When thebrine tank 21 is full of water, thewater inlet valve 23 in thebrine tank 21 shuts automatically and stops the water flow. -
FIGS. 27-30 are illustrations for the third embodiment. -
FIGS. 27 and 28 show another moving valve disk and another fixed moving valve disk of the third embodiment, respectively. - The structure diagrams and working principles of the third embodiment for the procedures of softening, backwash, brine in-taking and fast rinse are the basically same as the first embodiment.
-
FIG. 29 andFIG. 30 show the structure and the state of the valve and relative positions of the fixed and the moving valve disks in the cycle of regeneration. The throughhole 15 in the movingvalve disk 3 is aligned with the throughhole 11 in the fixedvalve disk 2, theblind recess 13 covers and connects the throughhole 9 and the throughhole 8 in the fixedvalve disk 2, and theblind recess 14 covers and connects the throughhole 12 and the throughhole 25 in the fixedvalve disk 2. The water flow from thewater inlet port 5 runs by the throughhole 15, enters the throughhole 11, and jets out from theejector nozzle 17 at the end of theleg flow channel 16. After jetting, the water flow causes negative pressure at the outlet port of theejector nozzle 17, i.e., thebrine inlet port 20 of thevalve body 1. The brine in thebrine tank 21 is in-taken by thebrine inlet port 20 through thewater inlet valve 23. The mixed flow of the brine and the water runs from the throughhole 25 to the throughhole 12 via theblind recess 14 and thedistributor 22, and flows into a bottom of thefilter element 18 and further passes through the resin layer where the brine is regenerated. The flow then runs by the throughhole 9, enters the throughhole 8 via theblind recess 13 and outpours from theeffluent outlet port 7. When the water level of thebrine tank 21 falls to the pre-defined point, thewater inlet valve 23 shuts automatically. - The third embodiment is designed to realize another structure mode of regeneration besides the first embodiment. The direction of the regenerated flow is opposite to the direction of water producing. The advantages of this mode include low brine and regenerated water consumption and high displacement ratio of resin regeneration.
- This present invention realizes different controlled cycles of softening, purification, backwash and regeneration of effluent by changing the different aligning positions of the through holes in the moving and the fixed valve disks. Thus designed, the present invention features easy operation and a compact structure, applicability for various industrial water treatment systems as well as household water treatment systems and improved quality of water treatment.
